I was getting the same error. Just use pgadmin4 version 6.15 or newer. It solved my problem.

I was getting this error because in Postgres version 15 and letter column "datlastsysoid" from the table "pg_database" has been removed. You can visit this link

So in this case you can use Postgres version 14 or earlier versions.

I had the same error while connecting lớn an old instance of PostgreSQL from pgAdmin-4. Remember that

pgAdmin III may not function as expected. Supported server versions (of pgAdmin III) are 8.4 lớn 9.4.

so pgAdmin-4 range starts from PostgreSQL 9.5

I've used just an older pg db version, and it worked!

When I got this error it seemed lớn be because I had installed pgAdmin (a newer version) separately from the full PostgreSQL install which included pgAdmin. I uninstalled the separate installation of pgAdmin this error went away.

In my own case, I had postgreSQL 14 and 15 installed. I removed the newer version I installed separately from the full PostgreSQL install which included pgAdmin, uninstalled postgreSQL 14 and removed the tệp tin (c:\Program Files\PostgreSQL\14\data) and it worked.

I updated both:

  • Postgres
  • PGAdmin4

Basically, I first uninstalled both Postgres và PGAdmin4 from my "Add or remove programs" panel (I'm a Windows user). I figured I needed lớn delete both, since PGAdmin4 runs on top of the normal Postgres (PGAdmin4 is just the GUI).

Next, I installed Postgres from the trang web using the official installer (just Google it lớn find). The installer also helps you install PGAdmin4 (1 installer for both). I did the normal setup, and now it works.

A bit of background on my own problem's context:

  • I created an AWS Lightsail PostgreSQL 16 database.
  • I was trying lớn connect lớn it, using my old PGAdmin4 (which was running on top of Postgres 13). Had the error you mentioned.
  • I tried JUST reinstalling PGAdmin4 -> still the same issue.
  • Next I tried lớn uninstall BOTH Postgres AND PGAdmin4 -> reinstall both again -> now it works.

Hope it helps whoever's facing the same issue!

Just try lớn remove the pgAdmin thư mục from the C:\Users\myusername\AppData\Roaming\pgAdmin and restarted the pgAdmin and it should work.
